Ruled over by the engineers of Clan Skryre, the underground realm of Darklair is a maze of tunnels and caverns beneath the forest. Alongside the dens of the Clanrats, laboratories filled with whirling machines and glowing warpstone fill the stronghold. It is here that many of the greatest Clan Skryre creations have been tested mostly on prisoners and Skaven slaves, and there is an extensive firing range and testing ground for this purpose.
